Linear Motion Quiz

What does the term "rate" in physics refer to?

• The total amount of something over time

• The rate of change or how much something changes over time

• The speed of an object at a specific moment

• The total distance covered in a journey

What is the formula for calculating a rate?

• Time taken divided by something measured

• Something measured multiplied by time taken

• Something measured divided by time taken

• Time taken minus something measured

Which of the following is an example of a rate?

Which of the following is an example of a scalar quantity?

• Velocity

• Force

• Speed

• Acceleration

Which of the following is NOT an example of a vector quantity?

• Velocity

• Acceleration

• Force

• Temperature

What does the magnitude of a vector represent?

• The direction of the vector

• The amount or size of the vector

• The speed of the vector

• The force of the vector

How is displacement mathematically represented?

• Δx = x_initial - x_final

• Δx = x_final - x_initial

• Δx = x_final + x_initial

• Δx = x_initial / x_final

Which of the following statements about displacement is true?

• Displacement is always equal to the total distance covered.

• Displacement is the total distance covered between the initial and final points.

• Displacement is not necessarily the total distance covered.

• Displacement is always positive.

Can displacement be negative?

• Yes, displacement can be positive or negative.

• No, displacement is always positive.

• Displacement is always zero.

• Displacement depends on speed, not direction.
